Reinstatement of distributed cortical oscillations occurs with precise spatiotemporal dynamics during successful memory retrieval.
Reinstatement of neural activity is hypothesized to underlie our ability to mentally travel back in time to recover the context of a previous experience. We used intracranial recordings to directly examine the precise spatiotemporal extent of neural reinstatement as 32 participants with electrodes placed for seizure monitoring performed a paired-associates episodic verbal memory task. By cueing...
متن کاملRecollective qualities modulate hippocampal activation during autobiographical memory retrieval.
Recent neuroimaging studies report preferential hippocampal engagement during autobiographical memory (AM) retrieval. Although the basis of this preferential activation remains unclear, it may be related to the temporal specificity, recency, or recollective qualities of AMs, such as detail, emotionality, and personal significance. Typically, however, these variables are confounded, and thus we ...
متن کاملWhen Misinformation Improves Memory.
In two experiments, we explored the effects of noticing and remembering change in the misinformation paradigm. People watched slide shows, read narratives containing misinformation about the events depicted in the slide shows, and took a recognition test on which they reported whether any details had changed between the slides and the narratives. As expected, we found a strong misinformation ef...
متن کاملCategory-specific cortical activity precedes retrieval during memory search.
Here we describe a functional magnetic resonance imaging study of humans engaged in memory search during a free recall task. Patterns of cortical activity associated with the study of three categories of pictures (faces, locations, and objects) were identified by a pattern-classification algorithm. The algorithm was used to track the reappearance of these activity patterns during the recall per...
متن کاملCortical Representations Are Reinstated by the Hippocampus during Memory Retrieval
The hippocampus is assumed to retrieve memory by reinstating patterns of cortical activity that were observed during learning. To test this idea, we monitored the activity of individual cortical neurons while simultaneously inactivating the hippocampus. Neurons that were active during context fear conditioning were tagged with the long-lasting fluorescent protein H2B-GFP and the light-activated...
